Arrays Arrays
^^^^^^ ^^^^^^
Array types are also supported. They can be made of bytes, words or floats, strings, and other arrays Array types are also supported. They can be formed from a list of bytes, words, floats, or addresses of other variables
(although the usefulness of the latter is very limited for now):: (such as explicit address-of expressions, strings, or other array variables) - values in an array literal
always have to be constants. Putting variables inside an array has to be done on a value-by-value basis.
Here are some examples of arrays::
byte[10] array ; array of 10 bytes, initially set to 0 byte[10] array ; array of 10 bytes, initially set to 0
byte[] array = [1, 2, 3, 4] ; initialize the array, size taken from value byte[] array = [1, 2, 3, 4] ; initialize the array, size taken from value
